Application October 28. 1929. Serial No. 402,884 r,

v The mainobject of this invention is to provide a closure for radiatornecks, oil tanksand the like which maybe quickly'removedand applied, theopening being effectively sealed and the closure being compact andprojecting but 5 slightly above the neck on which it is mounted.

A further object is to provide a closure hav ing these advantages whichis very simple and economical in its parts and at the same time strongand durable.

Objects pertaining to details and economies of my invention willdefinitely appear from the description to follow. The invention isdefined in the claims.

A structure which embodies the features of my invention is clearlyillustrated in the accompanying drawing, in which:

Fig. 1 is a fragmentary vertical section on a line corresponding to line1-1 of Figs. 2 and 5 through a radiator structure embodying the featuresof my invention.

Fig. 2 is an inverted view of the closure.

Fig. 3 is an inverted view of the closure disk or plate removed from thebody of the closure.

Fig. 4 is a plan view of the gasket.

Fig. 5 is a plan view of the radiator neck.

In the embodiment illustrated 1 represents a motor vehicle radiator and2 the shell. The radiator is provided with a filler neck 3 having aninturned flange 4 at its upper end providing a gasket seat. On the inneredge of the flange I form opposed segmental cammed keepers 5 havingstops 6 at corresponding ends thereof.

The shell 2 is provided with an opening adapted to receive the neck 3and having a flange 7 embracing and spaced from the neck as shown inFig. l.

The closure comprises a body member 8 which is preferably formed as adie casting and has a depending flange 9 embracing the upper edge of theflange 7 of the shell. This body member does not constitute an actualclosure but is an ornamental part adapted also as a hand-piece.

The spring disk 10 constitutes a closure proper and is mounted on adepending stud or boss 11' disposed centrally of the body member 8. Thisstud 11 has lugs 12 engaging the opening 13 in the closure disk so thatthe disk is secured against rotation on the stud. The closure disk iscrowned somewhat and is provided with an nular corrugations 14.

At its outer edge the closure disk has a downturned flange 15 embracingthe neck '3 and centering the closure thereon. A gasket 16 is arrangedwithin this flange to coact with the 5 Claims. (Cl. 220 v flange on theradiator neck which constitutes a gasket seat. 7 p Y .The' latch member17 is providedwith an opening 18 engaging the lugs and is secured uponthe stud bymeans of thescrew 19 threadedinto the stud. ,Aspring washerindicated at 20 is provided forthe screw.

A gasket or packing 21 is arranged on the inner side of the closure diskso that a tight joint is provided between the closure disk and the bodymember. The latch member is provid- 8 ed with projecting lugs 22 adaptedto be engaged with and disengaged from the cammed keepers I 5 by arotative movement of the closure.

My improved closureis very economical in its parts and the parts areeasily assembled. At the 7 ers on the edge thereof, said keepers havingstops at corresponding ends thereof, a shell having an opening thereinto receive said neck provided with an upwardly projecting flangeembracing and spaced from said neck, a closure comprising a body memberflanged to embrace said flange on said shell and having a centrallydepending stud provided with a lug, a closure disk mounted on said studand having an opening therein to receive said lug, said closure diskhaving a downturned flange at its outer edge adapted to receive saidneck, a gasket arranged within said flange of said closure disk, therebeing a packing gasket between said closure disk and said stud, a latchplate arranged in supporting engagement with said closure disk andhaving an opening therein to receive said lug, said latch plate having\projecting lugs coacting\ with said keepers, and a screw threaded intosaid stud for clamping the said closure disk and latch member thereto.

2. The combination of a neck having an inturned flange providing agasket seat, said flange having oppositely disposed cammed keepers onthe edge thereof, said keepers having stops at corresponding endsthereof, a closure comprising a body member having a centrally dependingstud provided with a lug, a closure disk mounted on said stud and havingan opening therein to receive said lug, said closure disk having adownturned flange at its outer edge ber adapted as a hand'piece andhaving a central depending stud provided with a projecting lug, aclosure disk mounted on said stud to engage said lug whereby it issecured to rotate with said body member, said closure disk having adownturned flange at its edge eoacting with said neck, a gasket arrangedwithin said flange, a latch member provided with projecting lugsengageable with said keepers of said neck and having an opening toengage said lug on said stud, and a screw threaded into said body memberfor retaining said latch member and closure disk in position thereon.

4. In a closure, the combination of a neck having internal keepers, aclosure body member adapted as a handpiece and having a centraldepending stud provided with a projecting lug, a flanged closure diskhaving annular corrugations mounted on said stud to engage said lugwhereby it is secured to rotate with said body member, a latch memberprovide with projecting lugs engageable with said keepers of said neckand having anopening to engage said lug on said stud, and a screwthreaded into said body member for retaining said latch member andclosure disk in position thereon.

5. In a closure, the combination of a neck having internal keepers, achambered body member, a spring closure member mounted at its centerwithin said body member and against relative rotative movement thereto,said closure 'member having a downturned flange at its outer edgeengaging said neck, and a latch member provided with lugs coacting withsaid keepers.
